FIELD: power engineering; surge protection and ac power extraction devices. SUBSTANCE: device designed for surge protection of coaxial transmission line carrying high-frequency signal and ac current and for ac power extraction from coaxial transmission line has its arrester made in the form of gas-discharge tube with central conductor and conducting case. Device has inductor for ac power extraction whose reactance is high at high-frequency signal frequency and low at ac current frequency as well as capacitor for passing high-frequency signal whose reactance is low at high-frequency signal frequency and high at ac current frequency. EFFECT: enlarged functional capabilities; simplified design. 7 cl, 37 dwg
